2010-08-11mmc: fix all hangs related to mmc/sd card insert/removal during suspend/resumeMaxim Levitsky
If you don't use CONFIG_MMC_UNSAFE_RESUME, as soon as you attempt to suspend, the card will be removed, therefore this patch doesn't change the behavior of this option. However the removal will be done by pm notifier, which runs while userspace is still not frozen and thus can freely use del_gendisk, without the risk of deadlock which would happen otherwise. Card detect workqueue is now disabled while userspace is frozen, Therefore if you do use CONFIG_MMC_UNSAFE_RESUME, and remove the card during suspend, the removal will be detected as soon as userspace is unfrozen, again at the moment it is safe to call del_gendisk. Tested with and without CONFIG_MMC_UNSAFE_RESUME with suspend and hibernate.

2010-08-11mmc: split mmc_sd_init_card()Michal Miroslaw
This series adds support for SD combo cards to MMC/SD driver stack. SD combo consists of SD memory and SDIO parts in one package. Since the parts have a separate SD command sets, after initialization, they can be treated as independent cards on one bus. Changes are divided into two patches. First is just moving initialization code around so that SD memory part init can be called from SDIO init. Second patch is a proper change enabling SD memory along SDIO. I tried to move as much no-op changes to the first patch so that it's easier to follow the required changes to initialization flow for SDIO cards. This is based on Simplified SDIO spec v.2.00. The init sequence is slightly modified to follow current SD memory init implementation. Command sequences, assuming SD memory and SDIO indeed ignore unknown commands, are the same as before for both parts. This patch: Prepare for SD-combo (IO+mem) support by splitting SD memory card init and related functions.

Use kmalloc() to allocate fdmem if possible. vmalloc() is used as a fallback solution for fdmem allocation. A new helper function __free_fdtable() is introduced to reduce the lines of code.

2010-08-11isofs: Fix lseek() to position beyond 4 GBJan Andres
isofs supports files larger than 4 GB by using multi-extent files. However an lseek() to a position beyond 4 GB in such a file will fail with EINVAL, because s_maxbytes in the isofs superblock is initialized to 2^32-1, and generic_file_llseek() checks against that value. I therefore suggest increasing the value of s_maxbytes to have full support for large files in isofs. With multi-extent files, file size is only limited by the maximum size of the file system (8 TB), so this seems a reasonable value for s_maxbytes.

2010-08-11vfs: only add " (deleted)" where necessaryMiklos Szeredi
__d_path() has 4 callers: d_path() sys_getcwd() seq_path_root() tomoyo_realpath_from_path2() Of these the only one which needs the " (deleted)" ending is d_path(). sys_getcwd() checks for existence before calling __d_path(). seq_path_root() is used to show the mountpoint path in /proc/PID/mountinfo, which is always a positive. And tomoyo doesn't want the deleted ending. Create a helper "path_with_deleted()" as subsequent patches will need this in multiple places.

2010-08-11vfs: add prepend_path() helperMiklos Szeredi
Split off prepend_path() from __d_path(). This new helper takes an end-of-buffer pointer and buffer-length pointer just like the other prepend_* functions. Move the " (deleted)" postfix out to __d_path(). This patch doesn't change any functionality but paves the way for the following patches.

2010-08-11vfs: __d_path: dont prepend the name of the root dentryMiklos Szeredi
In the old times pseudo-filesystems set the name of theroot dentry to some prefix like "pipe:" and the name of the child dentry to "[123]" and relied on a hack in __d_path() to replace the preceding slash with the root's name to get "pipe:[123]". Then the d_dname() dentry operation was introduced which solved the same problem without having to pre-fill the name in each dentry. Currently the following pseudo filesystems exist in the kernel: perfmon mtd anon_inode bdev pipe socket Of these only perfmon, anon_inode, pipe and socket create sub-dentries, all of which have now been switched to using d_dname(). bdev and mtd only create inodes. This means that now the hack to overwrite the slash can be removed, so for unreachable paths (e.g. within a detached mount) the path string won't be polluted with garbage. For these cases a subsequent patch will add a prefix, indicating that the path is unreachable. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-08-11fs/sysv/super.c: add support for non-PDP11 v7 filesystemsLubomir Rintel
This adds byte order autodetection (of PDP-11 and LE filesystems). No attempt is made to detect big-endian filesystems -- were there any?

2010-08-11V7: Adjust sanity checks for some volumesLubomir Rintel
Newly mkfs-ed filesystems from Seventh Edition have last modification time set to zero, but are otherwise perfectly valid. Also, tighten up other sanity checks to filter out most filesystems with different bytesex than we're using.
